JUDGE MARION BEDWELL, OF FAYETTEVILLE, TENN ACETYLENE-GAS GENERATOR.

Specification of Letters Patent.

Patented Oct. 3, 1916.

Application filed January 4, 1916. Serial No. 70,106.

To all 20 7mm it may concern Be it known that I, JUDGE M. BEDWELL, a citizen of the United States, residing at Fayetteville, in the county of Lincoln and State of Tennessee, have invented new and useful Improvements in Acetylene-Gas Generators, of which the following is a specification.

This invention is an improved acetylene gas generator, the object of the invention being to provide an improved machine of this kind which is cheap and simple in construction, is strong and durable, is automatic in operation and which can be recharged while the lights are burning and without affecting the lights and also without waste of gas.

The invention consists in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings: Figure 1 is a vertical central sectional view of an acetylene gas generator constructed in accordance with my invention and showing the same with the bell and carbid container lowered. Fig. 2 is a sectional view of a detail.

The usual tank is indicated at 1 and the gas reservoir bell at 2. Standards 1 rise from the upper end of the tank and serve to hold the bell straight, when the machine is charged with gas and the bell is raised. In accordance with my invention, I provide a container 3 which is arranged in the center of the gas reservoir bell, extends downwardly therein for a suitable distance from the top of the bell and also projects slightly above the top of the bell and is open at its upper end. At its lower end or bottom, the said container is perforated as at 1. An inner wall 5 rises from the bottom of the container for a suitable height and is spaced from the outer wall of the container. That portion of the bottom between the inner wall wall is imperforate so that the inner wall is arranged to form a seal chamber 6. This seal chamber receives the lower end of a sealing bell 7, which is secured in the container 3 by a bar or other suitable device 8 which bears on the top ofsaid sealing bell and is here shown as passing through openings near the upper end of the con A carbid magazine 'or holder 9 is arranged in and removable from the container 3 and bears on the upper end of the inner wall 5. Said carbid magazine or holder is open at its upper end, is perforated at its bottom and lower portion as at 10 and is provided with a centrally arranged guide tube 11. The bottom has an opening and is also provided with a closure therefor which closure is hinged at one side as at 10 to facilitate emptying of the contents of the carbid holder, when required. A U-shaped gas distributing pipe 12 is arranged in the tank 1 with its vertical intake arm 13 passlng up through openings in the bottom of the container 3 and carbid magazine or holder 9 and also through the guide pipe 11 of the carbid holder and is open at its upper end in the upper portion of the sealing hell 7. The vertical outlet arm 14 of said gas distributing pipe is arranged against and under the gas reservoir bell 2 and is pro vided with a check valve 15. The arm 14 of the pipe 12 is provided with a depending U-shaped trap l1- to receive such water as condenses from the gas in said pipe, and to keep the pipe air-tight.

I also provide a U-shaped gas service pipe 16 which has itsvertical intake arm 17 arranged in the gas reservoir bell and its outer, discharge arm 18 arranged without the tank 1, the said pipe passing through one side of the tank atthe bottom thereof as at 19 and being provided with a downwardly extendelement 8 its lower portion, being arranged in the seal chamber 6 is eifectually sealed to prevent escape of gas. lVhen the gas reservoir bell 2 moves downwardly the lower portion of the container 3 and the lower portion of the carbid holder 9 is submerged so that water is supplied to the carbid and gas is generated. The pressure of the gas then moves the gas reservoir bell together with the container, sealing bell and carbid holder up and as the gas'is expanded and consumed the bell slowly settles until the carbid is again brought in contact with the water and so on, the generator acting automatically as will be understood. The check valve 15 holds the gas in the generator and under moderate gas pressure.

7 central rod 26.

allows the light to keep burning while recharging the generator with carbld and without admitting air to the gas reservoir bell.

To prevent undue gas pressure in the ap paratus, I provide a counterweight 22 which is connected to the upper end of the container 3 and hence to the gas reservoir bell by a cord 23, which cord passes over suitable pulleys 24L, the Weight being suspended by the cord and being arranged at one side of the apparatus. The weight although not so heavy, as the bell and attachments carried by the bell, tends to exert an upward pull on the bell so that the latter will rise The weight may be varied to ena'le any desired gas pressure to be, obtained and may consist of detachable members 25 arranged on a Having thus described my invention, 1 claim i 1; An acetylene gas generator comprising a water tank, a gas distributing pipe having a vertical intake arm arranged in said tank, a gas reservoir bell in said tank, a container carried by and depending from thetop of the bell, said container being open at its upper end, and being provided with a bot tom having a guide opening through which said intake arm of the distributing pipe extends, the bottom being also provided with a perforated portion, an inner wall on the 'bottom of the container arranged around the perforated portion, spaced from the outer wall thereof, arranged around the perforated portion of the bottomso that a seal chamber is formedbetween said inner and outer walls; a sealing bell movable in the container and sealed in the seal chamber thereof, means to detachably secure the sealing bell in place, and a carbid holder arranged in the container, bearing directly on and supported by said inner wall of the container and having openings in the bottom within the periphery of the inner wall for the reception of water when submerged and arranged in the container.

2. An acetylene generator comprising a water tank, a gas distributing pipe having a vertical intake arm arranged in said tank, a gas reservoir bell in said tank, a container carried by and depending from the top of the bell, said container being open at its upper end and being provided with a bottom iaving a guide opening through which said intake arm of the distributing pipe extends, the bottom being also provided with a perforated portion; an inner wall on the bottom of the container spaced from the outer wall thereof, arranged around the perforated portion of the bottom so that a sealing chamber is formed between said inner and outer walls, a sealing bell movable in the container and sealed in the sealing chamber thereof, meansto detachably secure the sealing bell in place, and a'carbid holder arranged in the container, bearing directly on and supported by said inner Wall of the container and having openings in the bottom within the peripheryrof the inner wall for the reception or water; when submerged and, arranged in the container, said carbid holder also having a guide tube intowhich the intake arm of the distributing pipe eX- tends and being further provided with a perforated hinged closure for its bottom openings, said hinged closure also having an opening through which the intake arm of the distributing pipeextends.

In testimony whereof I afi'ix my signature in presence or two witnesses.
